Abstract

Optische Empfangseinrichtung, die aus einem optischen Dämpfungsglied (1), einem optisch-elektrischen Wandler (2), einem Verstärker (3) und einer automatischen Pegel­ regelungsschaltung (4) besteht. Das optische Dämpfung­ sglied (1) besteht aus einem elektro-optischen Modulator, dessen Dämpfung von der automatischen Pegelregelung­ sschaltung (4) elektrisch eingestellt wird. Optical receiving device consisting of an optical Attenuator (1), an optical-electrical converter (2), an amplifier (3) and an automatic level control circuit (4). That optical attenuation element (1) consists of an electro-optical modulator, its attenuation from the automatic level control circuit (4) is set electrically.
